M. Charles Joly has issued a little work entitled Etude sur le Materiel Horticole, which reviews and does justice to the numerous horticultural exhibits of the Paris Exposition. These exhibits consisted chiefly of plans of some of the chief parks and gardens of Europe. Rockeries and grottoes on the ground: greenhouses and greenhouse plants, horticultural instruments, implements, ornaments, literature, and the bedding plants by which the grounds were ornamented.

We do not find that there was anything of the immense collections of hardy trees and shrubs which gave such an attraction to our own Centennial, and when we remember that one American firm offered to place one thousand species and marked varieties of ligneous plants on the grounds, and was refused permission to do so on the technical ground that his government had not recognized the exhibition. Under these circumstances it seems but retributive justice to learn from M. Joly's review, that an immense space originally intended for foreign exhibits was not filled, " mais, dans les derniers temps, ont fait modifier les dispositions premiers et oblige les horticulteurs a gamier les espaces non occupes".
